LIQUID TREATING APPARATUS File June 6, 1927 3 Sheets-Sheet 3 I XI 'EXTOR Patented Dsc. 1o, 1929 UNITED STATES PATENT NOFFICE- MGE JIINSEINI',j OF L08 ANGELES, CALIFORNIA LIQUllD-TBEATING APPARATUS idly changing the temperature of the liquid.

,lt has been found desirable to change thex temperature of various liquids in a minimum length of time and in a mannerwhich will prevent deterioration ofthe liquid g" as, for example, in the treatment of heavy density liquids to raise their temperature extremely f careful handling must be observed in orderto prevent accumulation of the dense material upon the heating surfaces to cause this material to become scorched and a similar taste to 5 be imparted to the liquid. 1t is the principal object of the present invention, therefore, to

provide means whereby liquid may be rapidly heated without deterioration due to heat or rapidly cooled in a minimum period of time. 2@ 'lhe present invention contemplates the use of an immersion heating or cooling element which may be submerged in a body of liquid to be treated and which is thereafter agitated M to cause its radiation surface to come into contact with a maximum amount of the fluid recurrently within a minimum period of time whereby greater heat transfer will take place than is accomplished when the liquid is suby@ `stantially motionless with relation to the heating or cooling medium, making the device particularly applicable for use in emulsifying, pasteurizing, cooling and otherwise 'treating liquids to change their temperatures.

The invention is illustrated by way of example in the accompanying drawings in which- Figure l is a view in side elevation with parts broken away to disclose the structural au details and relation of parts of one part of the present invention. f

Referring more particularly to Figure 1 of the drawings; it will be seen that a pedestal, 10, is provided having a horizontally swing- 70 ing arm, 11, from which is supported a portable heating unit, 12. It is to be understood that while thev descri tion of the device as here disclosed particu arly refers to the submerged. movingy coils as heating elements, 75

that the invention is 7similarly adapted for use with cooling mediums and for the` purpose of lowering the temperature of the liquids in which the coils are submerged.

The pedestal 10 comprises a base portion, 13, 80 Y cnr yin a tubular column, 14, which extends vertically. This column is closed by an end wall, 15, .at its lower end and a cover member, 16, at its up er end. Extending downl wardly through the cover member 16 and for 85 a considerable distance within the column is a pipe, 17, which may 'be in communication with a supply of steam when the device is to be used for heating purposes. The How of steam through the pipe 17 is controlled by a 9o S l Figure V3 55 valve, 18.' lThe wall of the steam pipe 17 within the column is perforated so that the steam may pass into the column and. may

end of the overflow pipe, 19, when it has ac# Mounted upon the column and fixed with rerespectively, are rove.

cumulated to a desired volume.' ditdrain valve, 20, is connected with the lower end of 'the column and permits all of the condensate to be drainedirom the column if desired.

lation thereto is a supportingcollar, 21, having a radial ball rail, 22, on its upper face and against which a 'bearing collar, 24, may rest.

The bearing collar is ree to rotate around the column and serves as a support for the track structure 11'. This structure, as particularly shown in Figure 2, of the drawing, comprises a pair of parallel tracks, and 26, along which wheels 27 and 28 may run and on the axle 29 between said wheels a block, 30, may be supported. The outer end of the track structure is provided with 'a cap, 31, to which a guy wire, 32, is secured. This wire is as.

tened at its other end to a collar, 33, which is free to rotate around the column 14 and is held in spaced relation to the collar, 24, by a series of bolts, 34. By this arrangement it will be seen that the track structure may swing around the axis of the column in horizontal plane and will at the same time permit theV block 30 to move toward and away from the column as convenience dictates.

The block 30 carries a pair of pulley wheels, and 36, around which ropes, 37 and 38, One end of each of said ropes is secured to a counter weight, 39.

-The opposite ends of the ropes passdown- Wardly through opening 40 in the center of the counter weight and are secured to the circulating head, 41, of the heating unit 12. This head is shown more in detail in Figure 3 of the drawings, where it will be seen that it comprises a central tubular shaft, 42, which extends vertically through stuing boxes 43 and 44. The stuiling boxes-form a part of a `distributor casting, 45, formed with an inlet fitting 46 and an outlet fitting 47, both of which iittings are disposed between the stuiling box ends of the casting and are separated by a partition wall, 48. This wall is -in the shape of a collar which lits between a central supply tube, 49, and the tube, 42, through which it extends.` The inside diamete'zfof the tubular shaft 42 and the outside diameter of the supply tube 49 are of such relation to each other that a return passage-f way, 50, will be formed between the walls of the two tubes and will permit liquid to flow out from the tubular shaft, 42, and into the fitting 47. An induction pipe, 51, is connected with thel inflow fitting, 46, and an vcarried upon the column 14. This pump is directly driven by a motor, 57, secured to a bearing, 58, upon this column and connected with the shaft of the pump ,through a suitable driving coupling,-` 59. The circulating pump 55 receives its supply off heated liquid from a tube, 60, which connects the pump with the f lower end of the column 14. The conduit 54 connecting with the eduction pipe 52 of the head is secured to the column at a point above the level of the pump so that a circulation of Huid may be had through the column and the pipes, as well as through the helical heating coil, 61, which is secured to the lower end of the tubular driveshaft, 42. The lower end of this coil connects with the inner supply tube 49 and the upper end of the coil connects withthe passageway 50 between the inner supply tube 49 and the tube 42. The tubular driving shaft, 42, after extending through the casting 45 and the stuiing boxes 43 and 44 at the opposite ends thereof, then extends upwardly into a gear housing, 62, where it is suitably journalled within bearings and receives a worm gear wheel 63. This wheel is in mesh with a worm gear pinion 64 and by which the tubular shaft is driven. The pinion 64 is provided with a flexible drive shaft, 65, connected to the end of a shaft with a circulating pump, 55, and

"driven by the motor 57. The motor oper- The motor is controlledrby a switch buti ton 66 carried on the handle grip, 67, of the head, 41. This button closes a helical circuit through conductors 68 and 69 carried in a conduit, 70, and leading to the motor 57, as well as to a source of electrical supply.

- In the .form of the invention particularly disclosed in Figures 1, 3 and 4 of the drawings, the heating element 61 is formed with upper and lower guard rings, 71 and 72. The lower end ofthe tubular driving shaft of the heating unit is litted with a bearing point 73 which may rest upon the bottom of a container/ 7 4 into which the heating element has been inserted. Due to the violent agitation of the liquid bythe rotating member 61 an vexpansion member, 75, is positioned'in the mouth of the container and prevents an overflow of the liquid when in motion.

ln the form of the invention shown in Figures 7 and 6 the construction and operation is substantially the same as shown in Figure 1, with the exception that the heating element 61 may be raised and lowered by mechanical means instead of the counter weight 39. 'lhe heating element in this case is mounted upon a'tubular shaft, 76, which extends upwardly through a tubular drive casing, 77, and is secured to the drive casing at its upper yend by an intervening collar, 76, which closes the space around the tubular shaft 76 and between it and the tubular drive member 77 The tubular shaft and the tun bular drive casing are suitably journaled in van upper bearing, 79, and a lower bearing, 66,.

'lhe upper bearing is htted with suitable stuling boxes to prevent a leakage `of fluid from around the shafts. 'llhe two bearings are carried by arms 61 and 82 forming a part of a sliding head structure, 63. This struc-l ture is mounted upon a vertical standard, 6l, and may be raised or lowered by the operation of a screw, 65, which passes through a nut, 66, carried by the head and which at its lower end is htted with gears,"67, and an op erating crank, 66, by which it maybe ro tated. The moving head, 63, is fitted with a motor supporting platform, 69, upon which a motor, 90, is carried.. 'lhis motor has a drive shaft, 91, directly connected to a worm pinion inI mesh with the worm wheel, 99.. 'lhe worm wheel is secured to the tubular drive shaft, 77, and rotates the same.. di suitable housing, 93, encloscs the worm wheel and also affords bearings for the tubular drive casing. Secured at the lower end of the tubular drive casing is a drip cup, 9d, which will prevent extraneous material from flowing down the shafts and into the liquid to be treated. id circulation of duid is effected through the heating element 61. The heating elementin thiscase is shown as being in the form of a double helix', one end of which connects with the central tube, 76, and the other end of which connects with the surrounding passageway between the tube and the driving casing 77. .d flexible conduit, 95, connects with the upper end of the bearing structure 79 and supplies a fluid which will pass centrally down through the tube 76 to one end of the tubular helix. A supply of fluid may be controlled in its How to this column from a pipe, 96, by a valve, 97. A

` return How of fluid from the other end of the 'heating element 61 is e'ected along the passageway occurring between the shaft7 6 and the casing 77 and thence through a plu rality of openings, 96,to a. return flexible con point o discharge.

In the operation of the form of the invention shown in Figures l to` 5, inclusive, a con taineris fittedwith the expansion collar, 7 5, and thereafter may be moved into the operat ing radius' of the device., llt will be understood that under normal conditions the heating element 61 is elevated above the normal top of the containers, and that a downward pull on the hand grip 67 will act against the counter weight 39 to cause the heating element 61 to be inserted into the container and submerged in the liquid. 'llt will, of course, be understood that theheating element may be properly positioned with relation to the container due to the fact that the supporting arm 11 may have radial movement around the standard l1d and that in addition the trolley structure permits the distributing head and the stirring element to be moved radially with relation to the standard.

vAfter the element 61 has been submerged in the liquid the switch button 66 may be pressedl to complete the motor circuit. 'llhis will simultaneously cause the heating element 61 to be rotated and a circulation of duid to be edected through the heating ele ment., 'llhe heating element will be rotated due to the fact that the 'motor 57 will drive the dexible shaft 65 which in turn rotates the worm gears 6d and-63 and imparts rotary motion to the tubular shaft t9. .dt the same time the circulating pump 55 will be set in motion and will cause the hot Huid from the standard 1d to pass upwardly from tube 60 through the pump, thence along flexible conduit 53 to the head, where the duid will then fflow down through pipe 51 to the induction AVthe dexible conduit 541 from which it is delivered into the upright 141'.

lt. will of course be understood that various liquids and duids may-be circulated through `the coil of the heating element 61, as for example, live steam, to obtain an extremely high temperature heat or a cooling medium when it is desired to cool the liquid.. y

ln "the form of the invention shown in litigures 7 and 6 of the drawings, the operation will be substantially identical with that previously described, with the exception that the circulating duid is delivered from a pipe 96 to a flexible conduit 95 and thereafter caused to circulate through the central tube 76 to the heating element 61, and then to be exhausted from the heating element through the casing 77 to a exible conduit 99. By manipulation of the cranh 88 the heating element may be duit, 99` which may be led to any convenient readily raised or lowered as convenience dici c tates.

vbe understood that various changes might be made' in the combination, construction and arrangement of parts b those skilled in the art without departing rom the spirit of the invention as claimed. f
